ALBERT M. SILBER, OF LONDON, ENGLAND.

MULTIPLE GAS-BU RN ER.

SPECIFICATION forming part of Letters Patent No. 229,765, dated July 6, 1880.

Application filed January 28, 1880. Patented in England August 7, I879. I

To all whom it may concern:

Be it known that 1, ALBERT MAROIUS SIL- BER, of No. 49 Whitecross street, in the city of London, England, have invented an Improvement in Multiple Gas-Burners; and I do hereby declare that the following descr ption, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from others of a similar class, together with such parts as I claim and desire to secure by Letters Patent-that is to say:

My invention relates to multiple gas-burners in which two or more burners producing flat flames, such as those known as bails-wing or fish-tail burners, are placed side by side, so that the flat flames issuing from them converge toward their upper parts.

The object of my invention is to improve the combustion of such burners, and I have found that this can be done by providing them with shields that have the effect of arresting cross currents and, giving them a direction favorable to the production of increased luminosity, as I will describe with reference to the accompanying drawings.

Figure 1 is a side view, and Fig. 1 a plan, of a duplex burner, consisting of two flat-flame burners, A A, placed side by side upon one supply-pipe. For such a burner I provide a single shield, B, which is a metal partition, somewhat wedge-shaped, situated midway between the two burners. Fig.2 is a side view, and Fig. 2 plan, of a triplex burner, consisting of three flat-flame burners, A A A, placed side by side. In this case I provide two shields, B B, one between each pair of the contiguous burners; and in like manner, as may be readily understood, for multiple-burners giving four, five, or more flames, I provide between each contiguous pair a shield, such as B, which has the effect of arresting cross-currents of air and directing them upward along with the flames.

I am aware of the patents on lamps granted to Gate and Putnam, November 16, 1841, and Clark, March 21, 1843, and I disclaim such, as they do not show my invention. These patents show a copper plate arranged between two wick-tubes and extending down into the lamp-body, for the purpose of conveying the heat of the flame to melt the lard or similar material to be burned. The objects to be attained are different from mine, the burners are different, and the results obtained by me cannot be secured in the construction shown in the said patents, because the plates between the Wick-tubes are of a less width than said tubes, and therefore cannot shield the flame outside the said copper plate.

Having thus described the nature of my invention and the best means I know of carrying it into practical effect, I claim- As an improved article of manufacture, the within-described multiple gas-burner, the body of which is constructed at its upper end with a series of bats-wing or fish-tail burner-tips, between which is arranged a rigidly-fixed upwardly-tapering shield, formed of a length and height greater than the burner-tips, as herein shown, for the purposes set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 6th day of January, 1880.

A. M. SILBER.
